Hi Evelyn,There is a big difference. You want Benadryl which is an antihistamine.It's action is to block histamine in the body which is responsible for the allergic reaction.Sudafed is a decongestant. It narrows the blood vessels in the nose. By narrowing, the nose doesn't get as stuffy nor does it drip so much.

If you have an allergy to a bee sting, you will know quickly and most likely will consider an ER immediately if you don't have a epi-pen.If you have a slight reaction, use the Benadryl at 50mg. It will make you sleepy. Apply ice to the area stung.Try to be with someone if it's your first sting. A serious reaction you will know right away. Get to the ER ASAP.Remember... The first allergy to something is usually a lighter reaction and the second one worse.Best wishes:-)

Benadryl is more for people who have allergies,itching,insect bites, and things like that. Sudafed is more for when you are sick and have a stuffy nose it's a nasal decongestant and benadryl is an antihistamine medicine. I hope this help with your question.

These are both wonderful answers. I just want to add if you are looking to take away itchiness or stinging after a bee sting or other bug bite (I only if you are NOT allergic) you can use witch hazel, hydrocortisone, Benadryl cream or Afterbite.

How I look at it is Sudafed is taken when you're having congestion in your sinuses or to counter the sedation from antihistamine medications. It constricts the blood flow in your body and can help you breathe better. Raises pulse and BP and dries you out. Benadryl is taken for essentially allergic reactions even if very minor and up to severe reactions but I'm sure better drugs exist. Hives, seasonal allergies and as a sleep aid are main uses I think but if taken above 50-75mgs it activates more receptor sites and can keep you awake and at doses around 150-200mgs it begins cause delirium.
